Douglas Laboratories Copper provides 2 mg of elemental copper in each capsule.
Copper is an essential trace element and functions as a cofactor of many enzymes involved in antioxidant defense (superoxide dismutase), connective tissue metabolism (lysyl oxidase), and amine metabolism (amine oxidases). Superoxide dismutase (SOD) is a key antioxidant enzyme in the body's cellular fluid (the cytosol) and mitochondria (the cell's powerhouses). SOD destroys harmful superoxide anions that are either generated during normal energy metabolism or coming from environmental pollution. Cytosolic SOD activity is dependent on sufficient levels of copper and zinc.
Many studies have shown that increasing dietary intake of these essential trace elements may increase the activity of SOD considerably. As the essential cofactor of several amine oxidases, copper assumes a pivotal role in the metabolism and degradation of amines. Monoamine oxidase is involved in the inactivation of catecholamines. It reacts with substances such as serotonin, norepinephrine, tyramine, and dopamine. Diamine oxidase inactivates histamine and polyamines. Histamine is produced by the immune system during allergic reactions in response to antigens. Lysyl oxidase acts on the lysyl side chains of collagen and elastin, providing the basis for cross-link formation within connective tissues.
Copper is also important in many aspects of iron metabolism (ceruloplasmin, ferroxidase), mitochondrial energy and phospholipid metabolism (cytochrome c oxidase), and dopamine metabolism (dopamine β- hydroxylase, tyrosinase). In the nervous system, copper is required for myelin formation and maintenance, as well as for normal neurotransmission. Absorption of free, ionic copper from foods is about 30-40% efficient, and can be severely compromised by free zinc and some antagonistic ligands in food, such as phytate. Compared to free copper, the copper amino acid chelate is more bioavailable and less influenced by antagonistic factors. Several studies showed that the Albion chelate leads to excellent tissue retention of copper, as evidenced by effective stimulation of SOD activity.
Copper may be a useful nutritional adjunct for individuals who wish to increase their intake of copper.
